In a voltage detection circuit, if a driving signal is provided from a control circuit to a drive target circuit that is one of a plurality of individual detection circuits, and a non-driving signal is provided from the control circuit to the other non-target circuits, switch portions of the non-target circuits are turned off to prevent a current from flowing through first transistors and second transistors of the non-target circuits, whereby generation of the output voltages in the non-target circuits is stopped, and a switch portion of the drive target circuit is turned on so as to allow a current to flow through a first transistor and a second transistor of the drive target circuit, whereby a voltage according to a voltage across both ends of an electricity storage cell corresponding to the drive target circuit is applied to an output conductive path.
